Application filed November 30, 1917.

To all whom it may concern:

Be it known that I, Enmnn L. Souunnonnn, a citizen of the United States,residin ct Southbridgc, in thecu'unt of Worcester ncl State ofMassachusetts, lave invented certain new and useful Improvements inOphthalmic Mountings, of which the following is u specification.

This invention relates to improvements in ophthalmic mountings and hasparticular reference to a novel and improved construction of frame ofwhat is commonly known as the \Vindsor type; that is to say, a framehaving certain metallic and certain nonrnetallic portions.

One of the leading objects of the present invention is the provision ofnovel and improved means for readily and securely connecting themetallic and non-metallic POP- 'tions ofthe mounting.

A further object of the invention is the revision of connecting meanswhich shall e qfiite ornamental in appearance when the mounting isviewed on the face of the wearer and which will securely retain theparts together. y

A further object of the invention is the provision of novel and improvedmeans for detachably connecting the ends of the nonmetallic rnme memberto the remainder of the mounting so that said frame member may bereadily removed or replaced as desired.

Other objects and ndvnntn es of my improved construction should .pnrentby referenceto the following speci cation taken in'eonnection with theaccompanying drawings, and it will be understood that I may make anymodifications in the specific details of construittion shown anddescribed within. the scope of the appended claims without departingfrom or exceedi-np the spirit of my invention.

Fig. XIII represents on end. vir ol' tin pa rts assembled Fig. XIVrepresents a fragm ntary per spective view illustrating the l'ornnuimiof the end of the non'metnllic frame member.

In the drawings I have shown spectacle mounting comprising a bridge orrenter l. and suitable frames at the ends of thc bridge for retaining inposition the lenses L. these frames preferably omprising the innermetallic frame member 3 and outer nonmetallic frame member 4, andemploying the end piece members 5 to detnchahly connect the ends of thefrunw. said. end piece members being held together as by the screws orfastening devices (3. one of which :it each end piece also serves as apivot for a temple member 7. It is to he understood. however,

that while I have here illustruhul and par ticularly described aspectacle form of con struction, that my invention is equally applicableto eyeglasses or other desired types of mountincs.

. In that fin-m of my invention shown in detail in Figs. II, III and IV,I have illus trated as secured to or into ra l with the frame at oneside the ham 8 having at its free end the offset ear 9 adopted to besecured as by the screw 10 to the adjacent end piece member, in use thenon-metallic frame being placed in position around the Til metallicframe and forced down tight] therengainst, when the hand 8 is bent. an

that the'frnme is securely held in place.

In F V to VII inclusive, I have shown ii modi ed form of my invention inwhich. in lace of the band 8 being secured at one the metallic frame atboth ends, but is of such size that the end of the non-metallic framemay be readily slipped inside the band, the non-metallic frame beingprefen ably formed with a groove or channel 11 to receive the band.

After the parts have been assembled and to securely hold the band inplace, I form on the end piece the offset 12 to form a seat for thetaper screw 13 which is passed downward between the band and frame andas it is tightened serves to form an outward loop at the one side of theband and to tightly draw the remainder of the band around thenon-metallic frame.

Figs. VIII and IX illustrate :1 nother form, in which the band 8 isfastened at the one end and is ioose at the other, the loose end beingadapted to be inserted in the slot 14 of the post 15, a screw driverbeing inserted in the slot above the band to turn the post, which may belocked in desired ad.- justed position by tightening of the nut 16,prongs 17 on the post 'interengaging with the end piece to aid inretaining the parts in position.

In Figs. X and XI, I have shown the band in place of extending entirelyaround the. non-metallic frame member as formed in a substantiallyL-shapc attached at one end to the frame and at the other end to the endpiece member, being adapted to be sprun outwardly sufficiently to allowthe end 0 the frame member 4 to be pressed or sun )ped therebem ath,when it will come bac into tight engagement with the frame, preferablyfitting within a suitable groove in the frame, and will suitably retainthe frame in place, While being entirely invisible when the mounting isviewed from the front.

A slight variation of this construction is illustrated in Figs. XII andXIV, in that the member instead of being exactly L-shape is of angularformation and is provided at the angle with an aperture adapted to receive a fastening screw 18 to most securely connect the arts, in thisinstance likewise the member icing bent outward somewhat as indicatedin. ig. XII, while the nonmetallic frame is placed in position and thenbent downward into the groove It) and there secured. through the use ofthe screw 18.

I claim:

1. The combination with a metallic frame, of a non-metallic frameextendingtherearound, bands on the metallic frame embracing the ends ofthe non-mctallic frame, and means for tightening the bands for firmlysecuring the parts together.

2. In an ophthalmic mounting the combination with a metallic framemember, of a non-metallic frame member extending therearound, a bandloosely secured to one of said frame m mbers, and means for looking theband in engagement with the other frame member for securely uniting theparts.

3. In a device of the character described, the combination with ametallic frame, and a (in-extensive non-metallic frame, of bands on themetallic fra me embracing the ends of the non-metallic frame, and meansfor adjusting the tension of the bands.

4. In an ophthalmic mounting, the combination with a metallic framemember, of a flexible band loosely carried thereby, a non.

' metallic frame member engaging the metal-- lic frame member,'.andmeans for securing the band in tight Pl'lgttgPTllBl'lb with the nonmetallic frame member to retainthe latter in position. i

In testimony whereof I have aflixed my signature in presence of twowitnesses itncsses H. v E.
